Mr. Müller, how was it at your house during the holidays? Did your guests have to freeze to save energy? No, it’s absolutely fine to heat. We don’t have every room in the apartment cozy and warm, but the living room definitely does.
Do you often have discussions at home about which lights should be on or how many degrees the heating should be? Last winter, yes. We held a competition among friends via WhatsApp group to see who would be the last to turn on the heating. I didn’t win.
